Need Analog supplies for exynosautov920, hence added new Analog supplies; 'a'vdd075_usb, 'a'vdd18_usb20, 'a'vdd33_usb20 Will add "full stops" for DTS coding style in description. > > > > required: > > - compatible > > - clocks > > @@ -235,6 +245,33 @@ allOf: > > > > reg-names: > > maxItems: 1 > > + - if: > > + properties: > > + compatible: > > + contains: > > + enum: > > + - samsung,exynosautov920-usbdrd-phy > > + then: > > + properties: > > + clocks: > > + minItems: 2 > > + maxItems: 2 > > + > > + clock-names: > > + items: > > + - const: phy > > + - const: ref > > + > > + reg: > > + maxItems: 1 > > + > > + reg-names: > > + maxItems: 1 > > + > > + required: > > + - avdd075_usb-supply > > + - avdd18_usb20-supply > > + - avdd33_usb20-supply > > Neither was this entire diff hunk here. > > This was part of other block for a reason. Added regulators in driver. This block is added for regulators (other block does not have "required" field for power supplies) if excluded this block, "make ARCH=arm64 dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/phy/samsung,usb3-drd-phy.yaml" will fail as mentioned below /home/pritam.sutar/workspace/auto/kitt2/projects/upstream/src/kernel/github/linux-next/arch/arm64/boot/dts/exynos/exynosautov920-sadk.dtb: phy@16480000: Unevaluated properties are not allowed ('avdd075_usb-supply', 'avdd18_usb20-supply', 'avdd33_usb20-supply' were unexpected) from schema $id: http://devicetree.org/schemas/phy/samsung,usb3-drd-phy.yaml# /home/pritam.sutar/workspace/auto/kitt2/projects/upstream/src/kernel/github/linux-next/arch/arm64/boot/dts/exynos/exynosautov920-sadk.dtb: phy@16490000: Unevaluated properties are not allowed ('avdd075_usb-supply', 'avdd18_usb20-supply', 'avdd33_usb20-supply' were unexpected) from schema $id: http://devicetree.org/schemas/phy/samsung,usb3-drd-phy.yaml# /home/pritam.sutar/workspace/auto/kitt2/projects/upstream/src/kernel/github/linux-next/arch/arm64/boot/dts/exynos/exynosautov920-sadk.dtb: phy@16500000: Unevaluated properties are not allowed ('avdd075_usb-supply', 'avdd18_usb20-supply', 'avdd33_usb20-supply' were unexpected) from schema $id: http://devicetree.org/schemas/phy/samsung,usb3-drd-phy.yaml# /home/pritam.sutar/workspace/auto/kitt2/projects/upstream/src/kernel/github/linux-next/arch/arm64/boot/dts/exynos/exynosautov920-sadk.dtb: phy@16510000: Unevaluated properties are not allowed ('avdd075_usb-supply', 'avdd18_usb20-supply', 'avdd33_usb20-supply' were unexpected) from schema $id: http://devicetree.org/schemas/phy/samsung,usb3-drd-phy.yaml# /home/pritam.sutar/workspace/auto/kitt2/projects/upstream/src/kernel/github/linux-next/arch/arm64/boot/dts/exynos/exynosautov920-sadk.dtb: phy@16520000: Unevaluated properties are not allowed ('avdd075_usb-supply', 'avdd18_usb20-supply', 'avdd33_usb20-supply' were unexpected) from schema $id: http://devicetree.org/schemas/phy/samsung,usb3-drd-phy.yaml# Note: These patches are being validated by enabling DTS (However, DTS patches are planned in next phase).
